Protocol for direct counterfactual quantum communication

TL;DR

This paper introduces a protocol using the chained quantum Zeno effect to enable information transfer between two parties without any physical particles traveling between them, challenging traditional assumptions in physics.

Contribution

It presents a novel quantum communication protocol demonstrating counterfactual information transfer without particle transmission.

Findings

Information can be transferred without particles traveling between parties in the ideal limit.

The protocol leverages the chained quantum Zeno effect for counterfactual communication.

Challenges traditional physics assumptions about particle-based information transfer.

Abstract

It has long been assumed in physics that for information to travel between two parties in empty space, "Alice" and "Bob", physical particles have to travel between them. Here, using the "chained" quantum Zeno effect, we show how, in the ideal asymptotic limit, information can be transferred between Alice and Bob without any physical particles traveling between them.
